Abstract
An image data correcting device included in a display device includes a correction data memory and a correction calculator. The correction data memory stores sampling window select information indicating a sampling window selected from a plurality of sampling windows that are different from each other, and correction data obtained utilizing the selected sampling window with respect to the display device. The correction calculator receives image data, and corrects the image data based on the correction data for pixels at positions corresponding to the selected sampling window indicated by the sampling window select information.

An image data correcting device included in a display device, the image data correcting device comprising:
- a correction data memory configured to store sampling window select information indicating a sampling window selected from a plurality of sampling windows that are different from each other, and correction data obtained utilizing the selected sampling window with respect to the display device;
- and
- a correction calculator configured to receive image data, and to correct the image data based on the correction data for pixels at positions corresponding to the selected sampling window indicated by the sampling window select information.
An image data correcting device included in a display device, the image data correcting device comprising:
- a correction data memory configured to store correction data that is obtained with respect to the display device utilizing a plurality of sampling windows at a plurality of reference gray levels, respectively;
- and
- a correction calculator configured to receive image data, to select at least one sampling window according to a gray level of the image data from among the plurality of sampling windows, and to correct the image data based on the correction data for pixels at positions corresponding to the selected sampling window.
A display device comprising:
- a display panel comprising pixels;
- an image data correcting device comprising a correction data memory configured to store correction data, and a correction calculator configured to receive image data, to select a sampling window from among a plurality of sampling windows that are different from each other, and to correct the image data based on the correction data for the pixels at positions corresponding to the selected sampling window;
- and
- a data driver configured to generate data signals based on the corrected image data, and to provide the data signals to the pixels.
